COMBINED CELLAR-'CUPBOARD AND DUMB-WAITER.

SPECIFICATION forming part of Letters :Patent N0. 628,828, dated July 11, 1899.

Serial No. 692i883. (No model.)

To @ZZ whom t 'nw/y concern.-

Be it known that I, GEORGE W. MENTZER, of Elgin, in the county of Kane and State of Illinois, have Vinvented a new and Improved Combined Gellar Clipboard and Dumb- Waiter, of which the following is a full, clear, and exact description. v

The object of this invention is to provide a simple and comparatively inexpensive cellarcupboard and dumb-waiter so arranged that it may be easily and quickly elevated from a cellar to a pantry or kitchen above and again lowered into the cellar to keep cool the articles contained therein.

I will describe a combined cellarcupboard and dumb-waiter embodying my invention, and point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional elevation of a cupboard and dumb-waiter embodying my invention, showing the same in its elevated position. Fig. 2 isa similar section, but showing the device in its lowered position. Fig. 3 is a sectional detail illustrating the manner of securing the hoistway frame' to -the floorjoists. Fig. 4 is a sectional elevation of a modification in which a well or cooling-chainber is made in the cellar to receive the combined cupboard and du mb-waiter. Fig. 5 is a side elevation of the combined cupboard and dumb-waiter. Fig. 6 is a cross-section of an adjustable guide employed. Fig. 7 is a bottom plan view of a portion of a shelf, showing a means for engaging and supporting it in the cupboard; and Fig. S is a perspective view of a locking-latchemployed.

Referring to the drawings, 1 designates the joists for supporting the iioor 2 of a roomsuch, for instance, as a kitchen or pantry 3- above the cellar-iioor- Secured to opposite joists is a hoistway-franie 5, made with four closed sides and open at the top and bottom. Extended outward from each of its corners at the lower end is a lug 6, which is beveled on its `upper side and has openings through which fastening screws or bolts 7 pass into the joists. These screws or bolts also pass 'throu gh slots formed longitudinally in wedges 8, arrangedbetween the lugs 6 and the lower edges of the joists. The object of beveling the upper sides of the lugs and employing the slotted wedges and portable hoistway is to accommodate the frame to diderent widths of joists and uneven iioors for ease of plumbing.

The door 2 has an opening 9, which is somewhat larger than the opening through the frame 5, so that when the top of the frame 5 engages closely against the under side of the iioor around the opening 9 shoulders 10 will be formed by said upper ends, for a purpose to be hereinafter described.

The dumbavaiter or cupboard 1l has a partition 12 across it near its top, forming the iioor of a compartment in which bre-ad or the like may be conveniently kept. The front of this compartment is preferably provided with laterallyJsliding doors 13 14. \Vhen the device is in its lowermost positiomthe portion 'of the cupboard or dumb-waiter containing the bread-compartment will be within the frame 5, so that the bread contained in the compartment will be somewhat protected from dampness in the cellar. Arranged within the combinedcupboard andy dumbavaiter are a number of shelves 15. These shelves will preferably be adjustable, so as to provide `for different heights or spaces between the shelves to accommodate them for different articles. As a means for holding the shelvesv as adjusted I have shown, particularly in Fig. v7, shaftsV 16, arranged at the ends of the shelves and adapted to rock in keepers 17. i At the ends of the` shafts there are outwardly extended iingers 18, which when the shelf is in position will project beyond the end of the shelf and into holes formed in the side walls of the combined cupboard and du rnb-waiter. In placing a shelf in position the` fingers 18 will be swung down ward somewhat on a vertical plane with the ends of the shelf. Then by placingthem in line with the holes formed in the side walls the shelf maybe lowered and the fingers` thus projected into the holes.

Attached to the outer side of the sidewalls of the combined cupboard and dumb-waiter are strips 19, which move in guides 20, depending fromthe frame 5 near the side of the combined cupboard and dumb'waiter.. As

clearly shown in Fig. 6, these guides 20 con- IOO sist of a fixed trough 2l, with the open side toward the combined cupboard and dumbwaiter, and arranged within the trough and movable transversely thereof are side guidestrips 22, which are shown as L-shaped in cross-section, and arranged within these side guide-pieces is an outer side guide-strip 23. The pieces 22 may be adjusted laterally of the trough by means of screws 24, and the strip 23 may be adjusted inward and outward by the screw 25. The object of these several adjustments is to compensate for the swelling or contraction of the guides or strips 19,

due to the temperature of the cellar and to irregularities in the guides. The guides are placed at the rear of the framework, so that they may at anytime be extended and braced.

Hoisting-ropes 26 are connected to the sides of the combined cupboard and dumb-waiter at its lower end and extend over pulleys 27, mounted in opposite side walls of the frame 5. Attached to the outer end of each hoisting-rope is a we ight 28.

It will be noted in Figs. l and 2 that the top 38 of the combined cupboard and dumbwaiter projects beyond the sides thereof and is designed to fit snugly in the opening 9 in the iioor and rest upon the top of the frame 5. This'top 38 when the combined cupboard and dumb-Waiter is in its lowermost position will have its top surface iiush with the upper surface of the floor 2 and practically form a portion of said floor. A draw-rope 39 passes through an opening formed at one edge of the top 38, thence downward at one side of the combined cupboard and dumb-waiter, .thence around pulleys 40 41, mounted in the lower portion of the sides of the combined cupboard and dumb-waiter, and thence up the opposite side and connects With one end of a latch 42, made in the form of an anglelever and pivoted at its center to the inner side of the frame 5. This latch at each of its ends has inwardly-projecting lugs 43, one of side of a stop 44, secured to the side of the ward by the weights 28.

combined cupboard and dumb-waiter. This stop 44 is made wedgc-shaped,with the smaller end downward. The object in making the locking-latch 42 in the form of an angle-lever and making the stop 44 wedge-shaped is to provide for the placing of said parts either to the right or the left alongside of the frame 5, as the convenience of the drawing-rope may require.

In the operation of the device above described by drawing upward on the rope 39 the locking-latch 42 will be rocked to move its lug 43 out of engagement with the stop 44. Then by still pulling on the rope 39 the combined cupboard and dumb-waiter will be moved up- It is obvious that the strain upon the rope 39 need be but very slight, as the weights are intended to do the lifting. Then the device is in'its lowermost ward movement of the device under the influence of the weights should such weights be made heavier than the combined. cupboard and dumb-waiter by the removal of some of its contents.

In Fig. 4 I have shown a well 45, formed in the ground 46 of the cellar and in which the combined cupboard and dumb-waiter may be placed for the sake of the coolness of said well. In this construction of course the guides 2O will be extended to the bottom of said Well and secured in any desired manner, and of course as .the combined cupboard and dumb-waiter shown in this modification is not intended to have its top form a portion of the floor .a trap-door 47 must be provided for the opening 9. The operation of this device (shown in Fig. 4) is substantially the same as above described, excepting that the draw-rope is differently arranged. In this example the draw-rope 48 is secured at one end within the frame 5, as at 49, then passed downward and around the pulley 50, then around the opposite pulley 5l,and then up and around a pulley 52, supported at any convenient distance above the door 2. Then the rope is carried down and around a pulley 53 in a fixed base 54, then around the pulley 55, and the opposite pulley 56, and the end fastened at 57 to the base. In order to prevent swinging motion of the cupboard when in its uppermost position, the strips 19 are expanded atl the lower end, as at 58. The parts 58 are just sufficiently expanded to move easily in the guides; but in practice the upper ends of the guides are slightly contracted, so as to engage snugly with the expanded portions for the purpose mentioned. The guides 20 (shown in Fig. 4) may be supported or braced by any desired number of braces, according to the depth of the well.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A combined cupboard and dumb-waiter, designed for movement from a lower room to an upper room and from said upper room to the lower room, consisting of a cupboard movable through an opening in the floor of the upper room, a hoistway-frame adjustably sehoistway-frame adjustably secured to the Hoor-joists, guides extended from said frame, the space between the guides at the upper end being contracted, strips on the combined cupboard and dumb-waiter movable in the guides IIC 1o having beveled upper sides, slotted Wedges arranged between said lugs and the lower edges of the josts, and screws or bolts passing through openings in the lugs and through Iohe slots in the wedges and intothe josts5 substantially as specified.

GEORGE w. MENTZER.
